Sharp and unsharp

A little glow can make the day

My piece on some of Irving Penn’s early work with a small negative got me thinking about how to emulate the effect using an all digital approach.

Aperture does not have the horespower to do these things, as we forever wait for plug-ins that do more than import and export files. So you have to resort to Photoshop, into which I roundtripped the file from my Aperture database. Thereafter, I applied Dave Beaman’s Ethereal Glow action. Download it, click on the downloaded file (this is for Mac users; Windows users will probably need some arcane incantations to make things work) and the action will become available in Photoshop’s Action menu which you can display from the Window menu. Click on the action, click the right arrow at the bottom of the Actions palette, wait a minute and you get the original transformed to the ethereal glow effect. Back into Aperture with the file and add sepia toning and you are done. Sure, you can mess with doing the glow effect in PS manually, but why bother when it has been done for you?

I did not add noise/grain as it did not work well in this example, but you get the idea. The effect is actually quite a bit more dramatic on a large print. Some parts of the resulting image are etched, some are glowing – not too far from Penn’s effort applyying re-photographing of the original and use of the point-focus enlarger, and a lot less work of course.

I’m not that keen on picture manipulation, but if that’s your thing there are dozens of actions to be found on that click-through page above.

Better sound

Not just for QTVRs

Good sound in a computer system is a nice thing to have, especially if you are interested in making QTVR pictures with sound or generally regard sound as part of the picture making experience. For those still in their first childhood I suppose these make for louder explosions with computer games – a genre, I confess, that leaves me in despair of the future of mankind.

Looking back on the Apple Macs I have owned, each has had sound worse than its predecessor. The iMac G4 ‘screen-on-a-stick’ came with decent separate speakers, and had so-so sound quality. The iMac G5 has downward pointing speakers, dictated by the slimness obsession at Apple, and had poor sound quality. The iBook G4 had upward pointing speakers – poor quality but not bad for the small size. And finally, the sound quality of the miniscule rear-facing (what were they thinking of?) speakers in the MacBook is simply execrable. Little volume and what there is comes out horribly distorted.

I checked around and the dominant approach seems to be USB-powered external speakers. These leave me unimpressed on paper as the maximum power they can generate, based on the modest current delivered over USB, cannot be great. Chat boards mostly concur. Then I chanced upon the Logitech Z-4i.

These come with a woofer/amplifier and two separates for mid-range and treble. A separate wired controller permits adjustment of the overall sound level and includes a small knob for adjusting the level of the woofer only. Neat and it works. If you like boom, crank it up. But it’s the power specs that matter here, for a device driven from the earphone outlet. Logitech states that each satellite can output 8.5 watts RMS, with the massive woofer putting out up to 23 watts RMS. That’s power!

In use they will play louder than most users will ever need and the quality white finish matches the MacBook perfectly. These are not remotely portable, but that’s the trade-off for good sound. The bulky woofer enclosure can be placed out of the way (mine is under my desk) as low notes are non-directional. The satellites go either side of your monitor. Plug these in and the MacBooks wretched, nasty little speakers are automatically switched off.

Recommended, especially at the $70 price (that’s about $69.95 more than Apple spent on the MacBook’s speakers) – an outstanding value. They come with a two year warranty and my listening to Horowitz playing Chopin’s Barcarolle as I type is as it should be. The rumble of the low notes on his magnificent Steinway Model D concert grand is not far from the real thing. True, the Steinway would be nice to have but is a tad spendy at $100,000+! Plus there’s the waiting list to endure …. still, I did get to touch it when it toured through Los Angeles a few years ago. Horowitz had two in his Fifth Avenue apartment in New York!

Snags? None so far.

Pushing it

Can you say ISO 3200?


5D, 200mm, ISO 1600, 1/60, f/4, -1 ev

One stop of underexposure and ISO 1600 – the sort of thing that would have film in tears. Par for the course with the low noise 5D’s sensor. I do wish the 200mm L lens had IS (1/60 is really slow with this focal length), but this will do for now.

Google goes QTVR

Now you can see your home – and so can everyone else

It may be invasive and doubtless the scum class (aka tort lawyers) will have a field day, but it sure is fun.

Check this link to see NY’s Metropolitan Museum in scrollable panoramic format with the newly enhanced Google Maps. It may not be QTVR quality but it certainly is clever.

The company doing all the pictures, or snooping if you are a tort lawyer, is Immersive Media.

Publishing with Blurb – Part I

A service with the requisite Gen Y silly name – is it any good?

That exemplar of street photographers, Juan Buhler mentioned in an email that his latest book of snaps was published using a web publisher named Blurb. He finds the quality superior to Lulu, which I used for my first book which was all monochrome. With the first book I uploaded a PDF file, created in MS Word (the bad old days before Apple’s Pages came along), to Lulu, and sure enough, what you see is what you get with this approach.

Blurb, by contrast, delivers an application named BookSmart to you by download and you use it to compose your book. There’s a broad selection of handy templates and while the whole thing is not especially fast, it more than suffices for composing a picture book. As my second book will be all color, I was intrigued to see what Blurb had to offer. Best of all, Blurb offers the option of a hardcover – the only way to go if you value longevity.

First, the software requires that files uploaded be 3000 x 2400 pixels, or thereabouts, to preserve quality. Make them smaller and your picture will show a large exclamation mark indicating the quality is insufficient for reproduction on paper. Given that all my high quality original pictures reside in the Aperture database, I wasn’t about to export them one by one (I’m aiming for 50 or so in the new book), as Aperture is as slow exporting pictures as it is in preparing them for printing – meaning dead slow. So instead I created a custom export profile for my pictures of choice which I highlighted in Aperture using Command-Click, thus allowing selection of non-contiguous originals. Here’s how the export preset screen looks in Aperture:

Note that I have set the Image Quality slider to maximum – twelve on the scale. DPI is set to 300 (not the more common 72 which is fine for screen display, inadequate for printing), as this is the density at which Blurb prints. Hence the large file sizes.

Here’s the export about to commence – the destination folder shows ‘Desktop’ but in practice I make a new folder and export there, to keep clutter down.

Thirty minutes later and there are 50 pictures in my book folder on the iMac (I cannot advise on PC use as I refuse to have a Microsoft paperweight in our home), with sizes ranging from 3-11 mB; some are from film, some from RAW files, so the file sizes are all over the place. These picture files are then imported into Blurb – another ten minutes or so, and after a bit of experimentation with the cover design, here’s what you see:

Pictures marked with a green check mark in the inventory tray at left are those which have been dragged and dropped into the book itself. Rearranging the pictures is a drag-and-drop affair and you can print one or two sided. I’m going to try both and will report back on how things look – I found with my first book that a draft print makes a lot of sense as it’s really the only way to determine if the book feels right from a layout and content point of view. I’m settling on an 11″ x 8.5″ landscape format with hard covers.

Narrative is easily added, but I keep it to a minimum. After all, this is a picture book, not a novel.

Time to do all this from start of export from Aperture to completion of upload to Blurb followed by the related formatting? 5 hours. This would be less on a second attempt, as there should be no learning curve. Blurb saves your uploaded pictures on the fly so if you lock up (I did, once) nothing is lost. Nice.

When composition is complete, the product must be uploaded using a broadband connection to Blurb. Here’s the Blurb upload in progress – it took 18 minutes on my so-so cable broadband connection. Not bad.

Overall I have found the BookSmart application provided by Blurb to be easy to use and reasonably flexible, providing many useful templates (techies can upload their own designs). The program slows down from time to time but simply exiting and restarting the application seems to solve the problem on my G5 iMac.

More when I get the first draft back. Meanwhile you can see the book at Blurb, together with a Book Preview, by clicking here. Don’t order it, please, as this is a draft proof to permit review and editing. Blurb automatically creates a Book Preview – click to see the first fifteen pages.
